The exhaust duct communicates with the outside of the vehicle temperature control seat 1. On the other hand, the connection duct 16, the heat exchanger 28a, with the drain port 36 for draining the water droplets such as rainwater from entering from the condensed water and the air blowing port 3 3 occurring on one of 28b are provided, connected A mouth 37 is provided.

One end of an air passage 38 extending from the air blowing port 33 is connected to the connection port 37. The air blowing port 33 is a connection portion between the seating side surface 6 c of the rear wall 6 a and the flexible wall 7 in the pad main body 6, and is provided substantially at the center in the left-right direction. A through hole (not shown) is formed in a connecting portion between the seating side surface 6c of the rear wall 6a and the flexible wall 7, and the cylindrical portion 42 of the air blowing port 33 is inserted into the through hole.
An outer flange portion 41 is formed on the distal end side periphery of the cylindrical portion 42. Then, only the outer flange portion 41 of the air blowing port 33 is exposed from the rear wall 6a and the flexible wall 7. The outer flange portion 41 is engaged with the skin of the rear wall 6 a and the flexible wall 7, and the air blowing port 33 is prevented from entering the rear wall 6 a and the flexible wall 7.

  Further, the cylindrical portion 42 of the blower port 33 has a base end opposite to the outer flange portion 41 extending downward, and this extended portion is a blower passage 38. One end of the air passage 38 opposite to the air outlet 33 is connected to the connection port 37.

That is, the waist pad 5 is provided so as to close the gap between the seat seat surface 2 and the seat back 3, and the back wall 6a so that the pad body 6 of the waist pad 5 surrounds the waist of the user. And two lateral walls 6b. For this reason, air pool Ar (refer FIG. 1) is formed in the location corresponding to the waist pad 5. FIG. And it becomes the form where the ventilation port 33 is arrange | positioned toward this air reservoir Ar.

  Further, as shown in FIG. 6, since the plurality of recesses 43 are formed in the outer flange portion 41 in the air blowing port 33 of the temperature control device 9, the user's waist K blocks the front of the air blowing port 33. Even if it is a case, cold / hot air is injected from the recessed part 43. FIG. For this reason, the air on the front surface (air reservoir Ar) of the waist pad 5 is reliably cooled or warmed.

Therefore, according to the above-mentioned embodiment, a user's waist circumference can be cooled and warmed efficiently, and a user's body temperature adjustment can be performed efficiently.
Further, the pad body 6 of the waist pad 5 is separated from the seat back 3, and the pad body 6 and the seat back 3 are connected by the flexible wall 7. For this reason, even if the vehicle temperature control seat 1 has a reclining function, it can be completely closed by the waist pad 5 between the seat seat surface 2 and the seat back 3. Therefore, an air pool can be reliably formed in the front surface of the waist pad 5, and a user's body temperature can be adjusted efficiently.

  Furthermore, since the seat seat surface 2 and the seat back 3 are not cooled or heated, it is not necessary to use a breathable cloth or porous leather for the skin of the seat seat surface 2 or the seat back 3, so that the water resistant structure It can be set as the temperature-control sheet | seat 1 for vehicles excellent.
